If instead of using this, I simply execute all the "doit"s sequentially from the REPL, they work fine and there's no crash. Here's (room) at the end of executing sequentially:Dynamic space usage is: 395,955,632 bytes.Read-only space usage is: 3,160 bytes.Static space usage is: 2,592 bytes.Control stack usage is: 2,880 bytes.
Binding stack usage is: 568 bytes.Control and binding stack usage is for the current thread only.Garbage collection is currently enabled.
